AUTOMOBILE-RADIATOR.

Specification of Letters Patent.

Patented Nov.. 2i, initd..

Application filled March 16, 1916, Serial No. 84,568.

To all whom t may concern:

Be it known that I, ROBERT G. MASON, a citizen of the United States, residing at county of Kings, State of New York, have invented a certain new and useful Improvement in Automobile-Radiators, of which the following is a full, clear, 'and eXact description.

My invention relates to improvements in radiators for automobiles and the like, and has for its object to provide an improved radiator, which may be connected up i-n the ordinary manner, said radiator being so constructed as to have the ordinary cooling ducts and surfaces and in addition a passage which may be used as a by-pass in order to return some of the heated water directly to the engine without passing through cooling passages.

Heretofore, automobiles have been provided with radiators and with by-passes entirely external to the radiator and some automatic means for controlling the passage of water through the bypass. This is an eX-v pensive construction, difficult to install, uncertain in operation, and inconvenient for various reasons.

By my invention I provide a compact construction in which theby-pass is very direct' and does not take up any space outside of the space now normally occupied by a radiator. The object of pass is to enable the operator of the car to control the temperature of the Water in the cooling chambers of the engine so that it may bekept at the temperature best adapted for the operation of the engine, it being well known that in the Winter time the water is sometimes cooled to too great a degree while inthe summer time as much cooling as possible is ordinarily desired.

The following is a description of an embodiment of my had to the accompanying drawings, in

which,

Figure l is a rear view of av radiator embodying my invention; Fig. 2 is a vertical section of the same on the line ace-a, Fig. l; Fig. 3 is a horizontal section'of the same on the line ywy, Fig. 2. Fig. 4 is a perspective showing certain details.

Referring more particularly to the drawings, l is a radiator frame inclosing the ordinary ducts 2 and cooling surfaces 3.

i is a bailie plate located above the cooling ducts, having perforations 5, which serve to providing the byi invention, reference beingdistribute the water more or less evenly over the whole top of the radiator ducts.

6 is a port which opens above the baille plate 4f.

7 is a chamber located below the cooling ducts which receives the water therefrom, which Water then-passes to the water chambers in the engine through the pipe 8.

9 is aby-pass contained within the radiator proper, being nested among the ducts 2 and consisting of a large vertical pipe connecting the chamber 7 with .a port l0. The ports 6 and l() are both connected to apipe ll, which leads from the upper end of the water chambers of the engine (not shown). Connected to an extension of the bailie plate 4 is a valve l2, the pivot of which carries a gear Wheel 13, with which meshes another gear Wheel 14, mounted upon a shaft l5, which leads to a knob and indicator 16 located on the dash of the automobile within easy access of the operator. By means of the valve l2 some or all of the water can be vdiverted around the cooling ducts in the radiator.

In operation the chauffeur turns the member 1G until the indicator is in any desired position, so that the valve l2 directs a corresponding proportion of waterthrough the by-pass and cooling ducts, thus procuring the desired temperature in a simple and eiiicient manner.

As will be evident to those skilled in the i art my invention permits of various modifications Without departing from the spirit thereof, or the scope of the appended claims. What I claim is:

l. In a radiator, the combination of a radiator frame, cooling ducts contained within said frame, a by-pass also contained within said frame, said cooling ducts and by-pass discharging into a common return, a valve controlling the How of Water to said cooling ducts and to said by-pass, and means for controlling said valve.

2. In a radiator', the combination of a radiator frame, cooling ducts contained Within. said frame, a vertical bypass, said cooling ducts and bypass discharging into a: common return, a connection having an upper port and a lower port, a valve coacting with said ports for controlling the flow of water to said cooling ducts and to said by-p'ass, means for controlling said valve, anda baille plate above said cooling ducts and by-pass and between said ports, so that Waer is (scharge from Said sL mont'aoned port above; said bae plaie.; the amount depending upon the poson of Said Vak/a En a aniaor, he cmnbnaton n n radiator frame, cooling ducts contained wihn said frame, a vertical by-pass also Contained.
